Shortcut-to-adiabaticity-like techniques for parameter estimation in quantum metrology
Marina Cabedo-Olaya, Juan Gonzalo Muga, Sofía Martínez-Garaot
Quantum metrology makes use of quantum mechanics to improve precision measurements and measurement sensitivities. It is usually formulated for time-independent Hamiltonians but tim…
Time-dependent harmonic potentials for momentum or position scaling
J. G. Muga, S. Martínez-Garaot, M. Pons +2
Cooling methods and particle slowers as well as accelerators are basic tools for fundamental research and applications in different fields and systems. We put forward a generic mec…
Noise Sensitivities for an Atom Shuttled by a Moving Optical Lattice via Shortcuts to Adiabaticity
Xiao-Jing Lu, Andreas Ruschhaupt, Sofía Martínez-Garaot +1
We find the noise sensitivities (i.e., the quadratic terms of the energy with respect to the perturbation of the noise) of a particle shuttled by an optical lattice that moves acco…
Trapped-ion Fock state preparation by potential deformation
M. A. Simón, M. Palmero, S. Martínez-Garaot +1
We propose protocols to prepare highly excited energy eigenstates of a trapped ion in a harmonic trap which do not require laser pulses to induce transitions among internal levels.…
